László Péter Zenai, the festival organiser and the head of the Hungarian Association of Publishers and Booksellers (MKKE), said the 1,700-square-metre area at the park would give publishers a quarter more space compared to the festival's former venue at the Budapest Congress and World Trade Center.
He added that last year's festival attracted 55,000 visitors.
The festival will fill the entire park, excluding the Palace of Wonders, providing sufficient space for a number of smaller events, including professional meetings, book launches, readings and award ceremonies, Zentai said.
The park's different buildings also offer the festival's organizers the chance to create thematic areas, Zentai said. For example, the reception building will present books for children and young readers, as well as text books and graphic novels. In the House of Future, Hungary's biggest publishers will show their latest publications.
Breat Easton Ellis, the 44-year-old author of Less Than Zero and American Psycho, will be the first American guest of honour at the festival. Ellis, who has called himself a moralist, though some critics see nihilism in his works, is one of Generation X's defining authors.
China, the festival's country guest of honour, will show at a 100-square-metre stand. With the Chinese publishers will also come one of the country's most famous dance troupes from Szechuan.
The festival will welcome its first Arab guest this year - Egypt - which will join publishers from some twenty other countries, including Portugal, Spain, France and Russia. The biggest country stand will again be Germany's.
The Millennium Park is located at the site of the former Ganz factory, built around the end of the 19th century. The area was given a facelift a hundred years later and transformed into a civic venue, complete with some of the original buildings and machinery.
